terrace on the Ohio River at Brilliant near Steubenville, Ohio, of a 
chert implement one inch and three-quarters long and three-quarters 
of an inch wide in its widest part, making the third instance in which 
glacial man is proved by satisfactory specific evidence to have been 
in Ohio. The discovery was made in the summer of 1893 by Mr. Sam 
Huston, the county surveyor of Jefferson County. Mr. Huston resides 
at Steubenville and is well known to many scientific collectors who have 
availed themselves of his services; while his familiarity with gravel 
deposits and with the indications of their being disturbed or undis- 
turbed is unexcelled by any one in the country. 
For a long time the railroad has been engaged in removing gravel 
from pits along the extensive glacial terrace below Brilliant Station, on 
the Cleveland and Pittsburg R. R., about seven miles south of Steuben- 
ville. While excavations were in progress two years ago, Mr. Huston 
was engaged in overseeing public work in the immediate vicinity. 
When operations were suspended for dinner, Mr. Huston went into the 
pit on one occasion, where his attention was attracted by the flat end 
of a chipped implement slightly projecting from the perpendicular 
face of the gravel which was being removed. The material at this im- 
mediate locality was well-washed sand with very few pebbles. The 
bedding and cross-bedding were very clearly displayed both above and 
below the implement, and it was perfectly evident that there had been 
no disturbance of the strata since their original deposition. 
The situation in the face of the bank was such that Mr. Huston was 
barely able to reach it with his hand by standing upon the slight 
amount of talus that was at the bottom. The implement was about 
half way up to the top of the bank, making it about eight feet below 
the surface. Mr. Huston conducted me to the locality, so that the 
evidence was collected by me upon the spot. The bank was sub- 
sequently worked off about twenty feet farther and then abandoned, 
but according to Mr. Huston the stratification was essentially the same 
as is shown in fresh sections near by. The evidence is so specific that 
there is no chance to question it in detail, since every item was care- 
fully noticed and has been clearly retained in Mr. Huston’s memory. 
The gravel terrace at this point is one of the most extensive in that 
portion of the Ohio River, and is part of a series of terraces traceable 
from Pittsburg down to Wheeling, and indeed throughout the whole 
length of the river as far as Louisville. There is no question among 
geologists as to its glacial age. - It corresponds precisely, in the Ohio 
River valley, with those along the Delaware, in New Jersey, and the 
Tuscarawas and the Little Miami in Ohio, in which relics of glacial
